A nuclear fusion reactor in China, dubbed the "artificial sun," has broken its own record to bring humanity one step closer to near-limitless clean energy.
Even if we crack fusion power today, I can’t see it being deployed cheaply enough and quickly enough to compete with solar/wind+batteries. By the time we could get production fusion plants up and ready to feed power into the grid, it’d be 2050 and nobody would be interested in buying electricity from it.
Even in a world already powered 100% by renewables, fusion is attractive for high energy applications. For a current example see training of LLMs. However there are Industries with immense power requirements like Aluminium smelting that could use fusion power as well.
So far humans have found applications for all energy they were able to produce.
I think if we figure out nuclear fusion there will be induced demand for energy, in applications that were previously infeasible: desalination via distillation instead of reverse osmosis, direct capture of CO2 from the atmosphere, large scale water transport, ice and snowmaking, indoor farming, synthesized organic compounds for things like carbon sequestration or fossil fuel replacement or even food, etc.
Geoengineering might not be feasible today, but if energy becomes really cheap we might see something different.
Long distance transmission creates enormous power wastage, and cities are rarely located in places ideal for large scale wind and solar. Fusion can help deliver power to urban centres, reducing the acreage needed for a solar farm.
There are also inland places in northern latitudes that benefit little from solar. Wind and fusion would be a great energy mix for those places.
Fusion would provide orders of magnitude more power than solar. There’s a limit on how much we can practically get from solar, fusion would allow us to exceed that.
‘Too much power’ has never been an issue, and will likely not be an issue ever with solar. There are multitudes of technologies, especially in industry, that are currently impractical because they would consume too much energy.
There’s a ton of stuff in industry and manufacturing that aren’t practical because of energy. A lot of processes could be run cleaner too, leading to better environment practices.
It seems like it’s probably too late.

Yeah, but there’s no prizes for producing way more power than we use. We’re not running out of space to put solar panels or batteries.

In three decades, having a power source that can be placed away from the elements is going to be a very good thing.
Maybe for deep sea or space?
With what infrastructure are we even going to use all this electricity?

What I would like fusion to do is power space ships
